Cohu (COHU) Q1 2026 earnings review
AI Demand Ignites Massive Revenue Acceleration
Cohu is decisively exiting the semiconductor equipment cyclical trough. First-quarter revenue surged 29% YoY to $125.1 million, driven by accelerating AI and high-performance computing (HPC) demand. More importantly, test cell utilization climbed to 78%, signaling a broad industry recovery that historically precedes capacity expansion. The company successfully reversed its Q4 margin compression, pushing Non-GAAP gross margins to 46.5%. With Q2 revenue guided to a blistering $144 million (implying 34% YoY growth), the narrative has shifted heavily toward offensive AI-driven growth.
🐂 Bull Case
Management increased the AI-driven compute addressable market estimate to ~$750 million and raised FY26 HPC revenue outlook to $80-100 million. They are successfully capitalizing on high-power test requirements.
Test cell utilization at 78% is the highest point in recent quarters. Historically, utilization crossing the mid-70s triggers broad-based equipment reordering from OSATs and IDMs.
🐻 Bear Case
Despite the non-GAAP turnaround, Cohu posted a GAAP net loss of $12.1 million, heavily burdened by $7.3 million in purchased intangible amortization and elevated GAAP operating expenses.
The earnings release heavily highlighted AI and HPC, but provided no update on the pace of the automotive and industrial recovery, which management previously described as 'elusive'.
⚖️ Verdict: 🟢
Bullish. The 34% implied YoY growth guide for Q2, an upgraded AI revenue target, and margins snapping back to 46.5% confirm that Cohu's strategic pivot toward high-power compute testing is yielding tangible financial results.
Key Themes
Accelerating High-Performance Computing (HPC)
The primary catalyst for Cohu's top-line beat is its penetration into AI applications. Management raised the FY26 HPC revenue outlook to $80-100 million, citing significant design win activity. As AI processors demand complex thermal testing (like the Eclipse handler's capability up to 3,000 watts), Cohu is successfully expanding its footprint beyond traditional mobile and automotive bases.
Macro Recovery: Test Cell Utilization Breakout
Test cell utilization reached 78% at the end of March 2026. This metric has steadily climbed from 72% in 25Q1. This macroeconomic indicator is crucial: as factory utilization tightens, customers are forced to transition from buying only recurring consumables (spares/kits) to ordering full systems to add capacity.
Software Strategy Gaining Traction
The integration of the Tignis acquisition with Cohu's analytics platform is leading to broader production deployments. This expansion deepens customer stickiness and represents a long-term shift toward a higher-margin recurring revenue profile.
GAAP vs. Non-GAAP Disconnect
A specific data point that contradicts the rosy top-line narrative is the GAAP operating loss of $11.1 million. While non-GAAP operating income reversed to a positive $3.2 million, the company is still absorbing $7.3 million in purchased intangible amortization and restructuring costs. True operating leverage remains masked by these adjustments.
Automotive and Industrial Visibility
While AI is booming, the PR was conspicuously silent on the automotive and industrial segments. In prior quarters, management noted recovery here was slow. If legacy markets remain muted, Cohu's growth will become highly concentrated and vulnerable to a single end-market (data center).
Operating Expense Creep
GAAP Operating expenses ticked up to $69.1 million in 26Q1, compared to $64.4 million in 25Q4. While some of this is driven by R&D for new product cycles, management needs to balance growth investments against the cost-control narrative established during the 2025 restructuring.
Other KPIs
Reversing. Adjusted EBITDA rebounded strongly from $3.8M in 25Q4 and a loss of $1.9M in 25Q1. The Adjusted EBITDA margin improved to 5.6%, showing the beginnings of operational leverage as system volumes return.
Stable. The balance sheet remains highly liquid following the $287.5 million convertible debt raise in late FY25. The company explicitly noted it did not repurchase any shares in 26Q1, preserving capital for potential M&A and organic AI investments.
Stable. Despite the surge in systems demand, recurring revenue maintained its 60% share of total sales, proving that the installed base is driving strong, high-margin consumable and service sales alongside new equipment.
Guidance
Accelerating. The midpoint of $144 million represents an explosive 34% YoY growth compared to $107.7 million in 25Q2, and a 15% sequential jump from 26Q1. This confirms that the test cell utilization improvements are translating directly into major system orders.
Key Questions
Margin Leverage at $144M
With Q2 revenue guided to $144 million, what is the expected non-GAAP gross margin fall-through? Can we expect a return to the 48% target model discussed in previous quarters?
Automotive & Industrial Update
The AI/HPC momentum is clear, but what is the exact status of the automotive and industrial recovery? Are you seeing orders stabilize, or is it still trailing other segments?
AI TAM Breakdown
You increased the AI-driven compute addressable market to $750 million. Can you break down how much of this expanded TAM is driven by thermal handlers (Eclipse) versus inspection/metrology (Neon)?
M&A Pipeline
With $488.7 million in cash and share repurchases paused, how aggressive is the current M&A pipeline, specifically regarding software and AI analytics capabilities?
